I have withdrawn and trade ETH from MEXC multiple times already and I am never charged more than $3 but when I swap ETH ERC 20 on Uniswap the gas fee is almost always $10 and few times over $10, why is it like this? Are DEXs suppose to be more costly normal centralized exchanges?

With Centralized Exchange you are not actually interacting with the blockchain network, the fee was defined by the exchange and on CEX you only charged with trading fee there is no blockchain transaction fee. But with decentralized exchange you are actually interacting and using the Ethereum Blockchain so the fee was affected by the network condition. What you could do is checking the average transaction fee on the blockchain before doing any transaction on the DEX.

So, the fee on DEX depends on the network condition? But I don't think the ETH network is congested. And there are now lots of alternatives to it which many people use the most because the fees on them are cheaper and then they are also faster than in ETH. But, the first thing that you said seems legit and might be the reason on why transacting on DEX is more costly than the CEX.

There is what we call a gas station for ETH where we can check the fee but before we initiate a transaction in a DEX, there will still be pop up telling if how much fee it will cost us to complete the transaction. I prefer this, and I still can decline it if I don't like what I see on my screen.
